Displaying ManyToMany Fields in Django Template - django

Question

Model:
class Specialization(models.Model):
SPECIALIZATION_TYPE = (
('S','Specialty'),
('Ss','Sub-specialty')
)
specialization_desc = models.CharField('Specialization',max_length=50,unique=True)
specialization_type = models.CharField(max_length=2, choices=SPECIALIZATION_TYPE)
active = models.BooleanField('Active',default=True)
def __unicode__(self):
return self.specialization_desc
class Person(models.Model):
GENDER = (
('M','Male'),
('F','Female'),
)
first_name = models.CharField("First Name", max_length=50)
last_name = models.CharField("Last Name",max_length=50)
middle_name = models.CharField("Middle Name", max_length=50, blank=True)
specialization_id = models.ManyToManyField(Specialization,
Template:
{% for per in person_list%}
<tr>
<td>{{ per }}</td>
{% for spec in per.specialization_id.all %}
<td>{{ spec }}</td>
{% endfor %}
</tr>
{% endfor %}
View:
p = Person.objects.all()
return p
I would Like to see a table like this:
FullName | Specialization |
My Name | Programming, Web Development |
I'm getting this instead
FullName | Specialization |
My Name | Programming | Web Development
Storing spec in a variable is not possible accdg to articles that I've read, that alone should have solved my problem
Storing data in dictionary from views is giving me object Person is not callable
Seems a dead end for me. Ideas?

Answer 1

I don't get your question.
Do you get the specializations in template and only need to display them differently?
{% for person in person_list%}
<tr>
<td>{{ person }}</td>
<td>{{ person.specialization_id.all|join:", " }}</td>
</tr>
{% endfor %}
Furthermore, don't suffix foreign keys and many-to-many relations with _id.
For foreign keys Django does it for you already, so in DB you end up with field_id_id.
For many-to-many a separate table is created and the specialization_id isn't created anywhere in the DB. Use more verbose name, like specializations instead.
